Highway 142 is a 2-lane limited-access road in Cumberland County, Nova Scotia, Canada. It links Highway 104 at Exit 5 in Salt Springs Station to the town of Springhill. The 6-kilometre (4 mi) highway crosses the Canadian National Railway main line about 4.5 kilometres (2.8 mi) outside Springhill. There are several logging roads that have access onto the highway.^[1]

The highway was built in the late 1960s as part of a political promise to Springhill residents who were upset that their town was bypassed by the new Trans-Canada Highway alignment on Highway 104; this being less than a decade after the town's economy had been hit by the Springhill Mining Disaster of 1958 which resulted in the closure of local coal mining.^{[citation needed]}

The entire route is in Cumberland County.
